A digital billboard on Nine Mile Road recently has been flashing a message from the FBI announcing that the agency is seeking information on the violence at the Capitol. The billboard announces that tips can be reported to the FBI by calling 1-800-CALL-FBI or visiting fbi.gov/USCAPITOL. "FBI headquarters has placed a general ad with a billboard advertising company, and so those companies run billboards or place advertisements on electronic billboards all over the country," said FBI spokeswoman Amanda Videll. "Wherever there is space, they just run them on whatever billboards they manage. It might run on that billboard as long as there is space and the companies are willing to do that. But they are placed at random.”
